我所在的 XML 课程有这个额外的学分。

我们正在测试将课程添加到时间表的日期，以确保它是在 1964 年 9 月 1 日或之后以及今天的当前日期之前或当天。

dateAdded 字段是正在测试的字段。相当于 [DateAdded >= 9/1/1964 AND DateAdded <= Today] 通过使用 MinInclusive 来测试 1964 年的日期，我们将使用 maxInclusive 来测试今天的日期，但我们被告知要使用 DTD操纵架构。是的，这样做很愚蠢，但既然可以做到，老师就希望我们这样做。

但是，他没有介绍如何创建通过使用 DTD 文件的 XSLT 文件进行验证的 XML 文件。我们已经完成了带有 DTD 的 XML 和带有 XSLT 的 XML，但还没有完成这三者。

I'm in an XML class that has this piece of extra credit.

We are testing the date a class is added to a schedule to make sure it is on or after 9/1/1964 and before or on today's current date.

The dateAdded field is the one being tested. Equivelant to [DateAdded >= 9/1/1964 AND DateAdded <= Today] By utilizing the MinInclusive to test for the date in 1964, and we are to utilize maxInclusive for Today's date, but we are told to use a DTD to manipulate the schema. Yes, it is silly to do, but since it can be done, the instructor wants us to do it that way.

However, he has not gone over how to do an XML file that validates through a XSLT file that uses a DTD file. We've done a XML with DTD, and XML with XSLT, but not all three.
